Interesting… Well I’ve looked at sales here in Central Europe and top fertilizer brands are:
Plagron (mainly soil growers and offers some great additives)
Advanced Hydroponics of Holland (mineral for hydro, popular with drip systems)
BioBizz (for soil growers)
… then big gap followed by
General Hydroponics
Canna
Atami / B’Cuzz
Metrop
